The (no filter) tracks were recorded output from gameplay on the WinUAE emulator
The other tracks were recorded from gameplay on a real Amiga 500.
The Amiga had a hardware filter that muted the samples a bit, probably to improve the early low quality samples. As samples got better it became common to turn this filter off. It was originally on in this game, but most will want to hear the music with the filter off these days so I recorded two versions of it.
Most would listen to or record this by playing the soundfiles on Eagleplayer on an Amiga or some other player in Windows. These actually produce a slightly buggy and incorrect result, so I opted for recording from actual gameplay instead.
